A software visualization technique allows a software application or portfoli o tobe visually analyzed to determine the extent and dep th of problems raised when converting an existing software application or portfolio to make application - orportfolio-wide revisions, such as those needed to re spond to the year 2000 problem or the conversion to Euro currency. The software visualization technique first generates or inputs statistical data on a number of different software metrics and statis tics about the conversion process, such as the data or currency dependent lines of program code, the types of affected code lines, and the sizes and complexities of the systems, subsystems and programs of a software application and of the applications forming a por tfolio. These metrics and statistics are then used to alter the appearance of variou s views of the software application, systems, subsystems, programs individual lines of the programs generated by various visualization tools of the software visualization techn ique. By interacting with the various views, an analyst can quickly and cost-efficien tly determine which portions of the application or portfolio need revision, and the optima l methods for implementing the revisions.
